ing Dear classmates, Have you noticed the phenomena that more and more teenagers around us wear glasses? Some of them got short eye sigh ted even ata very young age. This is because they don ’t get a good habit of reading or they overuse their eyes watching TV or puter games. But how to protect our vision? What can we do for good eyesight ? Perhaps there are some ways for me to keep good vision, however, taking regular outdoor activities is an evident solution. Secondly, eye-care exercises twice a day may not be neglected. Having a distant look at intervals during the class break is equally important. In addition, don ’t read in light which is either too dim or too bright .Don ’t read in the bed or ina moving car. It is high time that we took quick actions to protect our vision! Thank you!
